An equation is derived for the TG43 geometry function, G(r,θ) , of a linear brachytherapy source in terms of its active length. This equation is validated by comparison to published values. It is then used to calculate values of the geometry function for the Model 200 103 Pd seed, which is a segmented linear source. PACS number(s): 87.53.–j
